1. Control Description

DUAL CHANNEL VACUUM TUBE COMPRESSOR

The 1968 MkII is a 1U Tube/FET dual channel / 'stereo

bus' compressor which by design delivers a transparent

'open' sound even during periods of heavy compression.

The original Drawmer 1960 used a tube stage at the front

of the compressor, whilst the 1968 MkII utilisies a J-FET

(Field Effect Transistor) gain reduction circuit that operates

faster than an opto-isolator. The compressor uses a 12AX7

tube makeup gain amplifier where you can add, with the

Output Gain control, up to 20 dB of additional gain.

The need for a ratio control has been removed as the

compressor operates on the soft knee principle where the

onset of compression is progressive.

The 1968 MkII expands attack times to six choices: 2, 9,

15, 25, 30 and 50 ms. Release times come in three fixed

times (100ms, 500 ms and 1 second) and three program-

dependent choices--200 ms to 2 sec, 500 ms to 5 sec

and 1 to 10 seconds--all program-dependent and

automatic.

The 1968 MkII provides full sidechain access for connecting

The key features are as follows:

• 2 Channel Tube/FET Compressor

• 2 soft-knee compressors with variable threshold, attack, release and output gain

• Switchable BIG and BIGGER control on each channel

• Dual mono or true stereo link operation

• Side chain access and side chain listen facility

• VU metering of gain reduction and output levels

• Switchable +10dB mode on VU re-scales the meter for users working at 'hot' output levels.

• VU red warning glow to signify 'approaching clipping'

• Balanced +4dB XLR in/outs

INTRODUCTION

DRAWMER 1968

MkII

an external equalizer for vocal stressing or de-essing.

Featured on both channels is a switchable 'BIG' and

'BIGGER' mode which applies less processing to the

fundamental low frequency but still disciplines the upward

associated harmonics which if untamed can result in a

'boomy' or 'boxy' sound. The result - a solid bottom end

with enhanced sub-bass and a smoother, wider frequency

response overall. This lets the operator use more

compression on an overall mix with less pumping action

caused by a kick and/or bass instrument.

The outputs of Channels 1 and 2 are monitored on two

yellow illuminated VU meters - with a red warning glow to

signify 'approaching clipping'. A three-position switch

adjusts the meters to show either normal output level, gain

reduction or VU +10dB mode, which re-scales the meter

for users working at 'hot' output levels.

An output switch selects normal compressor output, hard-

wired bypass and sidechain listen.
